Thanks you both for getting back, i don't really understand what you mean in terms of how loud 104 dbs would sound but it does seem quite a lot of watts 75 for tweeter and 250 for woofer for such a small speaker quite unbelievable when my CM8 are 150watts each?. I currently have B&W CM8 and Rotel RCX- 1500 and it clipps before you really feel the music and thats what i want to feel it, Thats why i was thinking get these and a sub and maybe that would do the trick? as i don't want loads of separates. or can anyone recommend good loud active speakers thats good for dance music /house?

I think if you are getting the Rotel to clip you are either applying some bass boost or listening quite loud. You will probably need more efficient speakers, possibly PA based ones if you like it really loud!

Get an app for you phone to measure SPL (its rough but at least gives you some sort of impression).

@hoopsontoast thats the thing with the rotel you can't change the sound settings it has no bass or treble controls. I know the PA speakers would be the best opition but they would be to big for my bedroom

I have a pair of the ADM 9T, an earlier version, which I had in a 6+m x 5+m room. It was not possible to get them to run out of puff and this was checked with earplugs to protect my ears. The bass is of very high quality but I'm sure others might want more.

The latest models, the ADM 9RS/S, have more bass output so you could see later whether you need the sub. The AVI sub is £800 and the PV1D @ £1200, I know what one I would buy. It is the size it is for a purpose and was created to be a matched system with the 9 series.

Does anyone have or heard how loud AVI ADM9.1 go? thinking of getting a pair and pairing it with B&W PV1D but want the mid/high to me loud as i knoe the sub will do the base just fine. Thanks

Very loud indeed, I doubt that shear volume level will be an issue, bass response however might be.

ADM's have vey tight, controlled mid bass, say 80 to 300hz, compared to most speakers at this level. This can lead to them appearing to be a bit bass light for some tastes, particularly if you are talking about playing dance or house music at anything approaching subjective club levels.

A subwoofer may not be the answer, it should be rolling off, quite steeply above about 80hz and may not give you the mid bass kick that you want. Ideally you really need to know where the bass power is concentrated, in my experience it is usually at a higher frequency than you think, reinforcing the sub bass may make the rom rumble and shake but it is not going to do anything for the bass kick.

Back at the beginning of the month I started a thread "If you want a bigger bass............" extolling the virtues of a the Mackie HDR series active studio monitors. They have a prodigious bass output for their size and far greater kick than the ADM's, though the latter are a more sophisticated package.

That isn't true, Richard 42. One of the AVI MDs has a history of making unsubstantiated claims about his products, and there's not a HiFi forum where these haven't been queried .

Myself, I'm probably sure that the AVIs go plenty loud enough, and certainly sure that I'd never play them too loud anyway. That doesn't mean I think the comments made above are out of order, nor that the figures need scrutiny.

im all for scrutinising claims, and would like to see some proper independent analysis. It's hard for anyone to prove their credentials on a forum, but feels like there's a lot of copying and pasting going on.

If the OP would like to investigate the AVIs properly I hope he can get to hear some. I'd suggest going to AVI forum for a bit of help. There are a small number of dealers dotted around. There may also be some private owners that wouldn't mind some 100db+ demoing :).

Re. The out of order bit, did you see oldrics comment before it was moderated ? I'd guess that could be considered libellous.

The bass extension of the ADM9s will be improved by adding a subwoofer to the system. Although there are many people who are happy to use them without a sub so it may be worth listening to them on their own first to see what you think.

If you do decide that you want to use them with a subwoofer then I suggest that you consider the AVI 10" subwoofer because it's designed to be used with the ADM9 speakers so you're guaranteed that it will integrate seamlessly. It's also a bit cheaper than the B+W PV1D too. There are many people who use non AVI subs with the ADM9s and are happy with the results though.
